Arthur's Missing Pal is the CGI movie, featuring the characters from Arthur. It was first aired on PBS Kids Go! on August 18, 2006. It was later released to DVD on August 22, 2006. It was written by Ken Scarborough. It premiered on Starz in June 2021.
Pal goes missing after Arthur leaves for his friends' water balloon fight because Arthur has forgotten to feed Pal. However, he and Buster are certain that D.W. did it, but D.W. denies any involvement. Arthur and his friends mount a search throughout Elwood City for the missing dog.
Arthur is going to feed Pal when Buster comes and crashes into everything. D.W. is trying to go to the Mary Moo Ice is Nice Extravaganza. Arthur and his friends have a balloon fight and Pal waits to get fed. He drinks his water bowl Arthur told him about. He needs to pee, but no one knows. He tries to pee on the carpet but remembers that Arthur told him not to do so. He runs upstairs to D.W., but she shuts the door on him. Pal cries and whines to Arthur at the window but he gets hit by a water balloon from Francine, which distracts him from Pal. Arthur and his friends leave to the Sugar Bowl. Pal runs to the bathroom, where he tries to pee in the toilet like a person. He tries to step carefully but he flushes the toilet with his paws and falls into the toilet. Arthur says "It just wasn't fair. Francine was right there. Pal started to scratch the glass!" He remembers that he needs to walk Pal. He searches everywhere but doesn't find him. That's when the search starts. They all split up and look for Pal all over town. However, none of them find any sign of Pal. Then Arthur and Buster find Pal's pawprints, which Buster makes a cast of. At that moment, D.W. announces that Pal has gone missing and insults him. Arthur and Buster get suspicious and start questioning D.W. They find out that Pal was in the bathroom trying to get out of the toilet. Meanwhile, Pal is traveling all over town.
